    This project was preformed to supply Libretext Authors with videos on General Chemistry topics which can be used to enhance their projects.  Also, these videos are meant to act as a learning resource for all General Chemistry students.

    Cell diagrams:  Shows the components of an electrochemical cell in a symbolic way.  The electrode at which the oxidation occurs (anode) is placed at the left side.  A single line / is used to show the change in phase.

      Then the solution in contact with the anode. A double line // shows the boundary between the two 1/2 cells.  Then the solution in contact with the cathode,  a single line, and then the cathode electrode.

    For the reaction: Zn(s) +  Cu2+(aq)     ®  Cu(s) + Zn2+(aq)

    The cell diagram would be:  Zn(s)/Zn2+(aq) //Cu2+(aq)/ Cu(s)

    We can measure Ecell but we are interested in measuring the ½ cell potential (E°) for each 1/2 reaction.  The ° means all species are 1 M and at 1 atm.

    E°cell = E°(cathode) + E°(anode)
